SYNOPSIS

DESCRIPTION

The aio_suspend() system call suspends the calling process until at least
one of the specified asynchronous I/O requests have completed, a signal
is delivered, or the timeout has passed.
The iocbs argument is an array of niocb pointers to asynchronous I/O
requests. Array members containing null pointers will be silently
ignored.
If timeout is not a null pointer, it specifies a maximum interval to
suspend. If timeout is a null pointer, the suspend blocks indefinitely.
To effect a poll, the timeout should point to a zero-value timespec
structure.

RETURNVALUES

If one or more of the specified asynchronous I/O requests have completed,
aio_suspend() returns 0. Otherwise it returns -1 and sets errno to
indicate the error, as enumerated below.

ERRORS

The aio_suspend() system call will fail if:
[EAGAIN] the timeout expired before any I/O requests completed.
[EINVAL] The iocbs argument contains more than AIO_LISTIO_MAX
asynchronous I/O requests, or at least one of the
requests is not valid.
[EINTR] the suspend was interrupted by a signal.
